“…Compared with autumn and winter (September to December), the methane flux of IVCW in summer (July to August) was at a relatively lower level, which is in line with the findings of others (Søvik and Kløve, 2007). However, contrary to the methane emission law of most wetlands, these findings indicate that the methane emission in summer is higher than that in autumn (Chang, 2003;Salimi et al, 2021). The temperature in autumn is usually lower than that in summer (Denning and Kraus, 2011;Duan et al, 2005;Joabsson et al, 1999;Mander, 2003).…”

It is very important to control methane emissions to reduce global warming. In this study, an attempt was made to adjust the oxidation-reduction potential (Eh) by adding different mass of potassium peroxymonosulfate (PMS) (0 g, 31.25 g, 62.5 g, 125 g, 250 g and 500 g) to reduce methane from integrated vertical-flow constructed wetlands (IVCW). Results show that the reduced CH4 emission from IVCW was the highest with decreased by 43.5% compared to blank group (PMS=0), when adding 125g PMS. Importantly, the reduced CH4 from the root-water system of IVCW was higher than that of the stem-leaf system of IVCW, when adding PMS. It’s found that Eh not only has a significant correlation with CH4 flux, but also has a significant relationship between PMS quality, DO, water temperature and sampling time (yEh= -0.44XPMS + 6.82XDO + 0.38t - 264.1, R2 = 0.99). It concludes that PMS, as an oxidant, is a very feasible method for controlling methane emissions from IVCW. Further research may combine other methods such as microbiology, physical control and hydrology control for mitigating the CH4 emissions from constructed wetlands.

“…Moreover, the four mesocosms in each climate chamber were split into two managed and two unmanaged systems (two replicates for each group). The team managed the water level for the managed mesocosms and skipped the water level adjustment for the unmanaged ones (see water level management section) to understand how water level adjustment can change the response of peatlands in terms of respiration, net ecosystem exchange (NEE), gross primary production (GPP) and climate scenario (Salimi et al, 2021 (Salimi et al, 2021).…”

“…Inland fisheries have a particularly low carbon footprint in comparison with other food sources (Ainsworth and Cowx 2018 ), and wetlands are an important carbon sink (Sarkar et al 2020 ). Therefore, wetlands have remained vital in global carbon balance and climate change mitigation (Salimi et al 2021 ). A positive environmental change in aquatic ecosystem was observed in India after the COVID-19 lockdown and reported in electronic media; however, negative impact was marked on the fisherman community (Fig.…”

The COVID-19 pandemic has created unprecedented human health crisis in recent global history with rippling social and economic effects. The outbreak in India has resulted in emergency lockdown in the country for more than 2 months, and that caused decline in the catch, demand, and supply of fish. It has severely altered the life and livelihoods of the floodplain wetland fishers. These floodplain wetlands play a key role in socio-economic development of stakeholders, by generating employment and livelihood in the studied regions. In the present study, a systematic assessment was conducted to identify the impact of lockdown on floodplain wetland fisheries in India with the aim to evaluate the impact of the COVID-19 lockdown on wetland fishing, fisheries production, income, and food access. We conducted a rapid telephonic survey covering176 wetland fishers in 3 states to document the early impacts of the pandemic and policy responses on floodplain wetland fisher households. The majority of fishers report negative impacts on production, sales, and incomes. Fishers of three Indian states Bihar, West Bengal, and Assam lost 20, 25, and 9 fishing days, respectively. About 70, 60, and 55 % fishers of floodplain wetlands of the three states admitted that lockdown made them partially jobless. Fish harvest during March to May was 32, 44, and 20 % lower than the previous years in Bihar, West Bengal, and Assam. The fishers of Bihar, West Bengal, and Assam lost income of INR 10000/-, 12500/-, and 4500/- due to lockdown. The analysis also showed that 25% of fishers each responded moderate to severe psychological impact and anxiety symptoms due to COVID-19. Demand supply gap during the lockdown led to the in 20–40 % increase in farm gate price of fishes at the wetland level. The present study is the first of its kind in India to systematically assess the impact and discusses several magnitudes on floodplain wetland fisher livelihood, income, and food access and suggests strategies and decision support.
